In short
Counter-strafing means tapping the opposite movement key to stop instantly before shooting, because bullets spread widely while you move. Strafe, tap the opposite key, shoot as you stop.
Why it matters
While running, bullets spread widely. Letting go of a movement key slows you down gradually; pressing the opposite key stops you much faster.
How to counter-strafe
- Strafe with A (or D).
- Release it and tap D (or A) briefly.
- Shoot the moment you stop, then strafe again.
Drills
On an offline map, strafe between two points and fire one shot at the end of each strafe. Aim for a clean stop every time rather than speed.
